Hi,

I've been lurking in the forum, and developing with Activiti in the past few months - this is my first post.

I am currently working to implement a signal with a signal boundary event into my workflow, but running into a problem. I get the following exception message when I try to trigger the signal in a specific execution: Message: Execution '8' has not subscribed to a signal event with name 'signalFacultyCancel'.

I originally read this thread here: http://forums.activiti.org/en/viewtopic.php?f=6&t=4015&p=15579, and made sure I am doing every by the book to the best that I can tell. I am using the signal name and not the ID, and the signalRef attribute is mapped correctly. I have also confirmed through an ExecutionQuery that my process instance is indeed listening for the specific signal I am trying to trigger. At this point, I am out of ideas. Please advise.

My desire is to have a signal boundary attached to an approval task so that the submitter can cancel the request and end the workflow if the approval task is not completed. I am using the latest Activiti 5.10

Here is my signal:

<signal id="signalFacultyCancel" name="signalFacultyCancel"></signal>
‍‍‍

Here is the boundary event:

    <boundaryEvent id="boundarySignalFacultyCancel" name="boundarySignalFacultyCancel" cancelActivity="true" attachedToRef="divisionApproveTask">
      <signalEventDefinition signalRef="signalFacultyCancel"></signalEventDefinition>
    </boundaryEvent>
‍‍‍‍‍

Here is the calling code through the RuntimeService (using Groovy):

            def executionInfo = runtimeService.createProcessInstanceQuery().processInstanceId(bpmProcessId).singleResult()
            runtimeService.signalEventReceived("signalFacultyCancel", executionInfo.id)
‍‍‍‍

Exception stack trace:

I don't see anything wrong at first glance. Can you put the process (or a simplified version) in a unit test so I can test it (see http://forums.activiti.org/en/viewtopic.php?f=6&t=4637)
